' Another object of the invention is to provide a l windshield gasketwith conduit means for distributing heated air along a face of .theassoci ated windshield glass.

Other objects of the inventionwlll appear from the following descriptiontaken in connection with the drawing, which forms a lpart vof .this

specification, and in which: Y Fig; 1 is an elevational view of thefront porl tion of a motor, `vehicle, partly broken away to show theinvention associated therewith; Fig. '2 is a sectional view taken onlinie 2-2 of Fig. l showing the distributing portion. of the heatingsystemz Fig. 3 is a' sectional view taken on line 3-31of '30 Q Fig. 4 isa view similar to Fig. 3 but showing' a modied form of the invention.Referring to the drawing. by characters of reference,lIdindicatesgenerally a type/ of motor vehicle having an engine Il,enginehood .35 I2 .and'radiator I3 arranged and mounted .in a

conventional manner. Associated with the en-. gine is the usual exhaustgas manifold Il having an outlet conduit II extending therefrom.

The front end of theV bodyassembly is indi- 45' 'cate'd generally by thenumeral il and consists' ,of a cowl panel I1 and a-'vertic'allyextending frame member Il having a windshield il Vformed the in. Thebase 2 0 of this frame'mem` terminatesat its forward end in anups'tanding flange 2| which iswelded to a similar iiange 22 formed atthe rear end ofthe cowl panel; The base portion 2l extends rearwardly toform the instrument panel 23.

along the glass.

In the preferred form of the .invention the 50 provides a recess intowhich the edge portion of the windshield glassV engages and is sealed..The.

front wall 21 of the lower. length of gasket is formed with. a recess 2lfor receiving the welded together flanges 2| and 22,--so that Vthe jointis 5 V sealed and the gasket anchored to thebody.

'I'he gasket can be otherwise secured to the front assembly in the usualmanner. Associated with the gasket is a finish or garnish moulding Ilpreferably formed of sheet metal and fastened l0 to the frame member I!in any conventional manner, such as by screws or welding.

- .In order to prevent the accumulation of snow and the formation of iceon'the windshield glass various types of airheaters and air distributing15 systems have been employed. Some of these systems utilize heat fro mthe exhaust gas in the4 outlet conduit and provide distributingsystemsthat are auxiliary to the windshield structure. It is the purpose of thepresent invention tore- 20 duce the cost and improve the appearance ofvehicles v having windshield Aheating systems by uuuzing part of thewindshield structure as the heated air distributing means..

As a means of accomplishing'the invention I k25 propose to formfthewindshield gasket so that vit -serves the purpose of distributing heatedair to the windshield glass, and the manifold-or feeding j conduitcan beformed bythe garnish molding adjacent the gasket or can be. arrangedwithin the gasket. vIn either .event 4the wall 2l of the gasket isformedwith an extension-comprising a neck portion 3| and a head' 32. Theneckextends preferably at an angle rearwardly from the upper. end ofwall 2l sumciently to space the for- 35 ward lip Il thereof rearwardlyfrm the windshield glass. 'To insure this spaced relation of 'the lipfrom the glass, spacers I4 as shown in Fig. 3 can be formedlon thegasket. to projet.

.forwardly from the extension. The neck 3| is 40 Vprovided with aseries' of passages 2l extending therethrough which form thedistributingV means or outletsv for heated air. The angle of thepassages is as tc direct the air passing therethrough upwardly towardthe rear face of the' 45 Vwindshield abovethe wall 28 of the gasket. The

lip overhangs `the neck to some 'extent and assists in-directing theheated airl upwardly hollow moulding is formed with a slot .8l en-v.-closed by the gasket extension and in communication with the passages.The mouldingy and passages 3i will thus form a; manifold for dis@inenting heated an along tneymdsmeid glass. es

The interior of the moulding is connected by applications which willreadily occur to persons suitable means with an air heating system.Around the exhaust conduit I5 is a housing l having an inlet portionA lhousing afan (not shown). A conduit i2 is connected with the outlet endof the housing d0 and is ixed. to the underside of the base 2, the baseand the garnish moulding having openings through which heated air passesinto the moulding from such conduit.

In the form of the invention shown in Fig. 4, the hot air distributing'manifold is entirely within the gasket. A tube i5 is moulded in the neckportion of the gasket and is formed with a series oi outlet openings'iialong its upper face. These passages l-5 communicate with outletpassages il formed in the gasket neck opening toward the windshieldglass. The lip 33 of the gasket head in this instance overlies thepassages il to assistin directing heated air upwardly along the glass.Provision is made in forming the gasket for connecting the conduit l2with the tube 65.

,It is to be understood that the heated air distributing systemdescribed is not limited in its application to the lower length ofgasket kand moulding but can be used around the windshield as may bedesired. As shown in Fig. 2, a portion of the gasket and mouldingalongthe left side of the windshield is similar to those at the lowerport-ion of the Windshield and a branch conduit ii@ extends to themanifold at such side. In the main feeding conduit 42 is a valve 5| thatcan be operated manually to make the system effective or ineffective.'l

Air is drawn into the inlet 4I and moved through housing 40 where it isheated by the exhaust outlet conduit l5.I The heated air is forced fromthe housing through conduit 42, or l2 and 5E) to the manifold, either inthe moulding or the gasket and through the passages 35 or 4l to theWindshield glass.

By utilizing the windshield structural parts as the manifold ordistributing means cost can be reduced because separate apparatus forthis purpose is of course eliminated. As Athe manifold means, hereindescribed, is entirelyl concealed no vision obscuring space is requiredfor assembly of the device. v

Although the invention has been described in connection with a specicembodiment, the prin-z ciples involved are susceptible of numerous otherskilled in the art.

What I claim is:

l. A window glass gasket comprising a moulded body formed with a glassreceiving recess, said body having aV base portion and substantiallyparallel wall portions extending from the base forming a portion of therecess, a deflector lip formed along one edge of a body wall, and airpassage means extending through the base of the lip.

2. In a motor vehicle, a rubber gasket comprising a body having asurface for engaging the 'edge portion of the windshield glass, adeflector lip formed on the body, and means formed on the gasket forspacing the lip from the glass, said gasket having heated air conductingpassages therein opening between the detector lip y and the glassengaging surface.

3. A window glass gasket comprising a body having a surface for engaginga face of a' glass, a defiector lip beyond and spaced from the surface,and air passages having outlet openings between the defiector lip andthe surface.

4. A window pane securing and defrosting means comprising a pane ofglass, a gasket engaging the edge portion of the glass pane and havingair passages therein with the outer ends adjacent one side of the pane,hollow moulding means securing the gasket in position, the interior ofthe moulding means being in communication with the inlet ends of thegasket air passages, and a heated air system connected with the interiorof the moulding.

5. In a motor vehicle having a windshield glass, the combination of arubber gasket engaging the edge portion of the glass, said gasket havinga plurality of passages therein opening toward the face of the glass, atube embedded' in the gasket, said tube having openings thereinregistering with the passages in said gasket, and a heated air conduitcommunicating with the interior of said tube.

6. A window 'glass securing' and defrosting means comprising a rubbergasket directly encasing the edge portion of the glass, said gaskethaving a plurality of openings therein arranged to direct air againstone face of the glass beyond the encased edge portion, anchor means forthe gasket, and a heated air system communicating with the openings insaid gasket.
